Typically, donor contributions to the credit unions are targeted and used in the same statutory requirements and restrictions as the Mutual Financial Aid fund as a whole. Cooperation between credit unions, how they would not have been named, took place always, from the moment when the movement moved outside one credit union. Credit unions base their activities on savings of shareholders, their shares and savings contributions, which make up the fund of mutual financial assistance - a source of cash loans to shareholders. To increase the number of credit unions in 1979 was adopted the corresponding law that serves as the legal basis of their activity. Corporate alliances are intermediaries between credit unions and financial markets.
